What’s Your Preference?

If I get a D90, does it continuously focus while snapping at 4.5fps?
Or does it only focus once for the whole series of images?

I think that depends on if you are holding the AF button down. But if you are on continuous focus, it should try to focus in between shots.

you need to have it set in the AI Servo mode, so the AF tracks the moving object.
This will only work in the manual modes, not in the auto settings

(Talking from the canon side, but sure the same applies)

Thanks. Reason I'm asking is on my Nikon E8400 (high end coolpix back in '04) it only focuses once for the set of images. Even on continuous AF. Which is kinda stupid

Planning to get the D90 or it's successor soon.

No, it needs to be set to AF-C. The Servo mode is for a single-focus.
